Just a note for those having problems and in general. It seems the .OIV install is corrupted so anyone having problems with it, restore or delete your mods folder before you installed the OIV and instead use the manual install. When I did that it worked like a charm. And ofc don't forget to follow the description and use good gameconfig files and so on. TLDR; DON'T USE THE OIV. DO the MANUAL install instead.
